Poorly Bongo - the inevitable?

Post by TimC » Fri Mar 20, 2015 5:40 pm

Hello all

Our bongo is a bit ill.

Its been steadily loosing coolant - and had a couple of near overheating moments which the temperature alarm rescued.

At start-up its started missing badly and pumps out a lot of steam.

When its got a bit warm the header tank has been a bit pressurised.

Garage think head or head gasket.... thoughts?

Cheers

Sorry to hear your news. The symptoms do tend to point to head gasket or maybe cracked head. You may be get away with removing the head, having it skimmed, pressure tested & re-fitted. That's what happened in my case, but it never overheated as it just got pressurised & came out the header tank. If the temp has got too high then the chances of cracked head are much higher so it may be best to bite the bullet & replace it. It's all fixable if you have the time / money to repair it

Aye. Well I have bitten the bullet and ordered a new head, cambelt bits and a temp/coolant alarm. Ouch!

If it's any consolation I may be heading down the same road. My symptoms are less than yours but they point to something similar. Still, nearly 9 years of near faultless running and lots of pleasure and usefulness - I musn't grumble. I had a look on autotrader at what else I might fancy, but nothing else appealed, surprise surprise. I'm not ready to be normal :lol:

I'm with you there, Mike.

After 7 years of Bongoing absolutely nothing else will do. I just accept that the odd repair bill will come our way, but fancy new cars loose £££££££ on depreciation, you just don't get it as one bill.

Whisper this, but I know what was towing the fancy motorhomes around the site at the Golden Swan, shhhh.

Oh yes, I know what did an emergency Loo Rescue today. Traffic chaos near us, Bongo and camping loo dispatched to meet Mrs B.

I could go on...

Thanks all

Right, well this has got a bit more painful. The head has come off to find heat marking in the bores...along with some hairline cracks in one cylinder.

So it seems that block is toast...

I've got no idea what to do now...

Yep, get a complete motor from George at Bongo Spares, it'll have been pressure-tested and run to check that it's all ok.

Hi
You're really unlucky there, as I've never heard of the bores being damaged on a Bongo since I've been on here , and I've been on here since 2004...and I think I've only ever heard of a crank needing attention a couple of times...so it rather depends on budget...If you can wait for the repair, I'd have the whole thing overhauled with rebore/ pistons/ crank /head then you can almost guarantee many years of no hassle...
Cheers

Hi
I took that to mean the usual hairline cracks in the head???...but, yes, if it's the cylinder, that's definitely a goner!!!!!...more info?
If it is the case, then I'd go for one of these:

Add a new head, and you've got a new engine!....That would be my choice.

Maybe a good buy if in the UK .. but from Dubai and £250 carriage ..

Most UK Bongos seemed to get scraped for rust or head issues .. some engines have low mileage ..

Would it be worthwhile to lift / check the head .. repair if necessary .. refit with new gaskets ..??

Then you should have 100% peace of mind for many years to come ..

That is bad luck. I only know of one person who had a cracked block but he was somewhat lacking in mechanical empathy and drove it with insufficient coolant which caused its untimely demise.

Hi Mike...
But add it all together, and you've got a good running Bongo for less than a couple of grand , with years of hassle-free motoring, and most cars depreciate that kind of money in a couple of years!...There are one or two that seem to hold their money, and a good Bongo is now approaching VW money...I'm often on the "look-out"...what could be better...one of each!....Bongos are getting a "Kool" value of their own now!, and prices are trickling upwards!
